It’s a size most women dream of but Katie has managed to achieve her slim frame after shedding baby weight in less than one month.

While she’s adamant she’s ‘100% not on a diet’ and still enjoys her ‘chicken korma, rice and naan on a Friday night’, she’ll soon be undergoing intense training with personal trainer Hayler to get fit and healthy.

The mum-of-five, who welcomed her first child with Kieran, baby boy Jett, in August last year, said in her Now magazine column of her post-baby shape: ‘My body’s shrunk back already but I’m not really sure how. I certainly didn’t ping back into shape after Jett was born.

‘I know people may be surprised but don’t forget, I was under a lot of stress during the pregnancy and didn’t pile on the weight like I did with Jett.’

She added: ‘I’ve also been pregnant for nearly two years, so I think my body was ready to start getting back to my natural size.’

(Don’t worry, she didn’t actually have 24-month pregnancy. Can you imagine?! She fell pregnant just months after giving birth to baby Jett.

Katie went on to explain that her ‘personal trainer and nutritionist’ husband Kieran will be tackling her fitness in three weeks’ time and she hopes to have ‘the strongest and healthiest body I’ve ever had’.

So what’s her meal plan?

Breakfast: A massive fruit smoothie

Lunch: Fish and vegetables or a chicken salad

Dinner: Steak and homemade chips

Snacks: Packet of crisps and biscuits in the evening

We don’t know about you, but we feel a little tired just writing about keeping fit…
